Will not run on battery

have you installed all drivers of your laptop with xp compatible? better download it from lenovo site the drivers for windows xp.

If you are running on battery power and it powers off, then the battery is not fully charged or the battery is worn out or faulty.
Rechargeable batteries have a finite number of charge and discharge cycles and after 2 or more years they will lose its charge capacity until it will not charge at all.
A new battery will solve your problem provided the charging circuit in the laptop is OK.

You say the laptop all of a sudden flashed off.

How old is the laptop? You may have suffered one of two things? First of all, if the hard drive will not boot back up, even after using the recovery discs, then that would explain it powering off. I have seen this happen on old desktop hard drives.

Next, try to get the transformer or adapter tested. It may not be putting out enough amperage to run the laptop.

Appears the backlight for the LCD display has stopped working. This usually needs to be replaced by a professional unless you are electronically and mechanically savy.

Hi.. I have a temporary solution to your problem. I had the same problem. Remove the battery and the ac adapter from the laptop. Just reconnect the ac adapter without the battery and switch on the lap. Presto.. Problem solved.. It doesnt power off anymore unless u remove the ac adaptor. Usefull if u hav needed files n want 2 create a backup. Still i havent found out a permanent solution to this problem. I suspect its a motherboard fault

Yes Your Battery seems to be drained..you have to replace it..

Hello,

I had posted the Aug 19, 2008 comment about having this problem twice. I tried a new universal AC adapter, and it worked! (new adapter is a Targus APA63US) Now battery is charging and laptop also runs on AC alone. So perhaps it's an adapter problem instead of a battery problem. Get one at a store with a good return policy, so if it doesn't work for you, just return it. And if it does work, then happier days. I've had mine about 2 weeks. So far so good, though with what I've learned about Lenovo since having this problem, it wouldn't surprise me if something else goes wrong, or if the damn thing just blew up, ha ha. Also, this adapter set me back about $100 that I really should not have needed to spend! arrgggh ...

Cheers and Best of Luck and hope this helps other frustrated Lenovo owners!

Batteries have a memory,

When the battery was new it most likely would run for 1.5 hours, but, since you didn't want the computer to go off, and you were by a plug-in, you plugged it in before it was completely or maybe sometimes not even halfway discharged. That is where it stated its "memory" - this got shorter and shorter = your battery "THINKS" it is totally discharged and reads as so.

There are programs on the web (can't advertize for pay programs or give you links to them - against the rules) - that will re-vitalize your battery to almost new condition by discharging it more and more till it is truly fully discharged, then will fill it back to like new charge time.

Or you can buy a new battery.

SreeSatya,

Laptop batteries have a limited lifespan. When they reach the end of that life, this is how they behave. How old is your laptop?

I just replaced my Toshiba after three years. Unfortunately, laptop batteries are not cheap. You can find batteries for your system here:
